Security
1 high severity finding. You should review these findings carefully before considering using this skill.
W007: Insecure credential handling detected in skill instructions.
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
The skill includes an explicit plaintext password value ("password123") in a command example (agent-browser fill ... "password123"), which instructs the agent to output or embed a secret verbatim — a high-risk secret-exfiltration pattern.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
SKILL.md describes runtime browser navigation (e.g., `agent-browser open <url>`), and the AI snapshot workflow then ingests page-derived accessibility text (e.g., link/button/input labels) via `agent-browser snapshot -i -c`, which will reflect outsider-authored web content when the opened page is from a third party.
